my wicket apliaction created some pdf file. now I want to add button to print it somethink like this: how I can do it ?

Best Answer:

it looks you mix two things together. Your example is a javascript. It is not a PDF, it is just printing your document. It is equal as browser menu File -> Print, but the event is invoked from a javascript that handles button action. You can use the same button as in that example and add @print CSS to your web page to make your document nicely printable.

Also there is another way. If you want to print a PDF document from your application and you generate the PDF from Java code, look the following example for Wicket 1.6:

add(new Link<Void>("myPdfLink") {

    private static final long serialVersionUID = 1L;


    public void onClick() {

        byte[] data = ... // TODO your data

        final ByteArrayInputStream stream = new ByteArrayInputStream(data);

        IResourceStream resourceStream = new AbstractResourceStream() {                    

            private static final long serialVersionUID = 1L;


            public InputStream getInputStream() throws ResourceStreamNotFoundException {

                return stream;



            public void close() throws IOException {




            public String getContentType() {

                return "application/pdf";




            new ResourceStreamRequestHandler(resourceStream)
